"If the NRA is unable to collect donations from its members, safeguard the assets endowed to it, apply its funds to cover media buys and other expenses integral to its political speech, and obtain basic corporate insurance coverage, it will be unable to exist as a not-for-profit or pursue its advocacy mission", the court document says.

"In New York, we won't be intmidated by frivolous court actions from a group of lobbyists bent on chipping away at common sense gun safety laws that many responsible gun owners actually support".

Cuomo added, "If I could have put the NRA out of business, I would have done it 20 years ago".

Although the protesters showed up to the NRA headquarters, the organization said they were protesting an empty building.

Protesters were met with ardent opposition from counter-protesters who were separated by police and barricades.

The goal of the "National March on the NRA" is to push for revoking the NRA's tax-exempt status and to remember victims of gun violence. Organizers want universal, comprehensive background checks for all gun sales, and a ban on high-capacity magazines and assault weapons.

North was midway through his speech before he mentioned Marshall County High School, where the shooting occurred.

News media outlets report that inside the Friday event, incoming NRA President Oliver North received a standing ovation from about 300 people. He largely avoided the gun debate, focusing on topics such as patriotism and freedom. He said the best way to avoid the "murder, the mayhem, the madness" students experienced was better school safety.

"The NRA has encountered serious difficulties obtaining corporate insurance coverage", the gun advocacy organization said in an email to NPR.

A student is charged with murder and aggravated assault in the January 23 school shooting.

The NRA also claims it has lost insurance coverage to "safeguard its assets" and that NY pressured "insurance agencies, insurers, and banks into terminating business relationships with the NRA that were necessary to the survival of the NRA".

As a result, it said multiple financial institutions have entered into consent orders that compel them to end longstanding business relationships with the NRA in NY and elsewhere.
